As you may recall from a prior post, Callaway sued Acushnet for golf ball patent infringement back in February of 2006. The suit (1:06-cv-00091-SLR) alleges that Acushnet infringed 4 patents and has roots that extend all the way back to a previously settled 1996 lawsuit between Spalding and Acushnet.

The case is still very active and today I was stunned to see that Acushnet issued a subpoena to take the testimony of Phil Mickelson. If you don’t already know… Phil plays a Callaway ball. The deposition was scheduled to take place on October 25th in Irvine, California.

Now, I am sure that Phil is a bright guy, but what could a Psychology major have to say that would influence the outcome of a golf ball patent infringement lawsuit?

Regardless, I hope the deposition transcript is filed with the court so we can all read what Acushnet had to ask, and what Phil had to say.

Interesting stuff.
